To all whom it may concern:

Be it known that I, BERT L. GIFFORD, a citizen of the United States, residing at Barker, in the county of Niagara and State of New York, have invented certain new and useful Improvements in sprinkling or Spraying Devices, of which the following is a specification. v 7

My invention relates to sprinkling or spraying devices and more particularly to what is ordinarily termed the twirler member of a sprinkling or spraying device, and

on spraying nozzle, filed July 28, 1913, Serial 'No. 781,534.. r e

The primary object of my invention is the provision of a device of "this type equipped with a twirler member constructed to create a fog or mist, to eject a fine spray, or a drop spray resembling rain.

A still further object is the. provision of atwirler which will not become clogged in spraying insecticide liquid and by means of which the spray will be spread over a considerable area or be directed in a substantially straight line so as to confine the spray to a comparatively small area.

l/Vitl'. these "andother objects in view, my invention'consists in the novel features of construction and in the arrangement and combination of parts to be hereinafter described and more particularly pointedout in the subjoined claims.

' In the drawings Figure l is a side elevation of a sprinkling or spraying nozzle embodying my invention.

Figs. 2 and 3 are-llongitudinal sections through the sprinkling or spraying nozzle taken on planes at right angles to each other, with the twirler positioned withinthe nozzle so as to eject a fog or mist, or a fine spray.

Figs. 4 and '5 are similar sections with the twirler reversed within the sprinkling or spraying nozzle, in which position said twirler creates a drop spray, resembling rain.

Referring now to the drawings in detail like numerals of reference refer to like parts in the several figures.

The reference numeral 15 designates the sprinkling or spraying head or nozzle having attached thereto the liquid supply ipe 16. This head or nozzle is in the orm of a hollow casing or body portion provided with an internal shoulder 17 near its outer end. i

Situated within said sprinkling or spraying head or nozzle is a disk-shaped twirler 18 which bears againstthe internal shoulder 17 and has its outer face flush with the outer edge of said head or nozzle. Lying against said outer edge and also against the marginal portion of the twirler is a gasket 19 against which lies a disk 20 having an escape opening 21 arranged centrally therein, the gasket 19 serving as a packing to prevent escape of the sprinkling or spraying liquid and also as a spacing member to separate the disk 20 from the twirler by an The twirler comprises a flat substantially circular member having cut-away portions 24 at diametrically opposite points, and two convolute passages 25, one of the ends of these passages opening at the cut-away portions in the same transverse plane of at least part of said cut-away portions and the other end of each passage terminating 35 1 opening of the disk in a comparatively and overlapping the firstmentioned end of the other passage, thereby providing passages around a central raised portion 26. Said'passa'ges are directed graduallytoward the axis" of the twirler and are formed 1n one sideor face of the twirlen] It is to be noted that these passages are narrowest at their entrance ends, so that they are substantiall'y self-cleansing.

At points between the cut-awayportions "24 each twirler is provided on the opposite face with spacing flanges 27. The portions 24v cut away from the twirler are slightly greater than the face of the shoulder 17 7 sages 25, where it is given a whirling motion. It thence enters into the space or chamber 22 between the twirler and the disk 20 where it is broken up into a fine spray or mist and finally escapes out through the escape opening 21 in said disk. To a certain v extent'the sizeof the escape opening in the passing through'the diametrically opposite disk co'ntrols the fineness of spray.

Where a straightstream is desired the twirler is' reversed so that the liquid in spaces 28, shownin Figs. 6 and 7, enters the space or'chamber 22without whirling action, and'consequently escapes through the escape straight line.

Where it is desired to deluge an extended surface or area'with a spray'of large drops similar to rain,'the twirler isprovidedwith a number. of open1ngs-29wh1ch, as shown in Figs. '10 and 11, are arranged in a circular course. at the 'b'ottoms of the convolute pas j sages and which openings may be of difterthe space or inlarger quantities, the liquid thus entered fere-nt sizes. This ,permitsthe liquid to en- 'chamber 22 of the casin being carried in a spiral course with the liquid entering the convolute passages through the diametrically opposite spaces 28., Whenthistwirler is used, a disk having a larger escape opening is substituted for the disk 20. A twirler'of thistype can belquickly substituted for the twirler first described.

V itisdesired to use a twirler to deluge an extended area "or surface in a manner similar to rain and at times'use the same for spraying, a twirlerisuchoas shown in Fig. '12 may be used. This twirler has the Openings 29 therein, but aregulating plate 7 .30 is provided on the inner side of the twi-rler'with similar openings 31, it being .ficentral'ly and rotatably mounted on the twirlerso that in turning the same the openings 29 in the twirler may be opened to the extent desired, or entirely closed.

In Fig. 13 I have shown the inner walls of the convolute grooves 25 beveled, this being brought about by tapering the central portion 26 of the twirler. In spraying liquid insecticide, sediment and particles of foreign matter in the liquid often clog the nozzle, and by thus flaring the inner walis of the convolute passages, the tendency of the outrushing liquid is to free the grooves of all lodging matter, the latter being carried outward onto the central portion 26 of the twirler so as to leave the convolute passages-free.

Having thus described my invention, what I claim is,--

1. A nozzle comprising a casing having an internal shoulder, a'twirler seated against said shoulder and having a marginal cutaway portion and a convolute passage in one face of said twirler having one end thereof-opening into said cutaway portion, and a disk secured to said casing spaced from said twirler, said disk having a central exit opening.

2. In a sprinkling or spraying device, a twirlercom'prising a circular body having marginalcutaway portions at diametrically opposite points andhaving in one face thereof convolute passages, the passages being spaced throughout their extent from the centerof the body and each of said passages opening into one of said cutaway portions and overlapping the other passage.

3. In a sprinkling or spraying device, a

twirler comprising a circular body-portion having a flat unbroken surface and flanges extending from said urface at diametrically opposite points, said body-portion being cutaway at its edge between adjacent ends of said fianges.

4. In a sprinkling or spraying device, a twirler having a circular body portion provided at diametrically opposite pointswith marginal cutaway portions, flanges extending from one face of said circular body portion between said cutaway portions and convolute passages in the other face of said body portion, each convolute passage opening into one of said cutaway portions and overlapping the other convolute passage.

5. A sprinkling or spraying device comprising a casing having an internal shoulder, a twirler seated against said shoulder and having marginal cutaway portions at diametrically opposite points, passages in the outer face of said twirler opening into said marginal cutaway portions, said passages being spaced throughout their extent from the center of the body, a washer seated against the end of said exit tube and'closing the "marginal cutaway portions of said twirler, a disk seated against said washer and having a central escape opening, and

an annulus threaded on the said exit tube and bearing against the marginal portion of said disk.

6. In a sprinkling or spraying device, a twirler having a circular body portion, marginal cutaway portions at diametrically opposite points, convolute passages in one face of said body portion opening at one of their ends into said marginal. cutaway portions, and openings through said body portion extending from the passages to the opposite face thereof.

7. In a sprinkling or spraying device, a twirler having a circular body portion, marginal cutaway portions at diametrically opposite points, convolute passages in one face of said body portion opening at one of their ends into said marginal cutaway portions, openings through said body portion extending from the passages to the opposite face thereof, and means for opening or closing said openings.

8. In a sprinkling or spraying device, a

disk-shaped twirler having opposite marginal cutaway portlons, convolute passages in one face of said twirler spaced throughout their extent from the center of the twirler, the inner walls of said passages being tapered to render them non-clogging.

9. In a sprinkling or spraying device, a twirler having a circular body portion provided with marginal cut-away portions at diametrically opposite points extending from face to face thereof, convolute passages in one face of said body portion opening at opposite points, said body portion being cutaway at its edge between adjacent ends of said flanges and the edge of said body portion where cutaway between said flanges being eccentric.

' In testimony whereof I aflix my signature.
